With the introduction of a new, dual-band feed system for the company's 9.4m antenna, ASC Signal Corporation has extended dual X- and Ka-band capabilities across its full line of earth station antenna systems.

Now, ASC has expanded the versatility of its feed systems by incorporating low-PIM (passive intermodulation) designs that prevent X-band transmit and receive frequencies from interfering with each other on the same antenna.

"Government and military SATCOM decision-makers want to exploit the advantages of fast-expanding Ka-band capacity while preserving access to X-band frequencies," said Keith Buckley, President and CEO of ASC Signal. "No matter what the mission requirement, ASC now offers a high-performance, dual-band, low-PIM antenna system to meet it."

For more than a decade, ASC has pioneered excellence in the design of both Ka-band and X-band transmission systems, with a focus on mission-critical low-PIM feeds and antennas, and value-added multiband antenna systems.

The ASC Signal line of antennas also incorporates patented innovations including sub-reflector tracking (SRT) technology and advanced environmental control systems, along with its monopulse feed system and ASC's Next Generation Controller (NGC).

The SRT provides 6-axis tracking of the satellite beam while actively compensating for thermal distortion caused by changes in temperatures at the earth station location.

Resonator Gyro Achieves 25 Million Operating Hours in SpaceWoodland Hills CA (SPX) Jul 18, 2013
Northrop Grumman's patented hemispherical resonator gyro (HRG) technology, which is used for military and commercial space applications, recently achieved a major milestone of 25 million hours of continuous operation without a single mission failure.
Since February 1996, the HRG has been a vital component of Northrop Grumman's Scalable Space Inertial Reference Unit (Scalable SIRU) and its ... read more
